Super Bowl LI
This game remains one of Belichick’s most glorious moments because the result was insane. Nobody gave the Patriots a hope of achieving victory after the Falcons took a 28-3 lead. It should have been insurmountable but then Atlanta had a meltdown. It was one of the most dramatic comebacks ever.
The Patriots scored touchdown after touchdown as the Falcons wilted in front of them. Finally, they won 34-28 to complete the victory and win Belichick’s fifth Super Bowl as a head coach. Meanwhile, the Falcons never recovered from this defeat and went into disarray over the following seasons (via The Ringer).
